Dynamical aspects of the adsorption hysteresis phenomenon

Magnetic Resonance Imaging, 2007
Equilibrium and nonequilibrium transport properties of adsorbates in mesoporous Vycor porous glass have been experimentally studied using nuclear magnetic resonance techniques. With the known geometrical characteristics of porous glass and with measured self-diffusivities, transient sorption curves have been quantitatively compared to those predicted ...

Dynamic Hysteresis Behaviour of Respiratory System Mechanics

Biomedical Engineering / Biomedizinische Technik, 2013
The static pressure-volume (PV) curve of the respiratory system is characterized by hysteresis behaviour. Determination of separate inspiratory and expiratory compliance is required to analyse this phenomenon during the dynamic situation of mechanical ventilation.

Role of hysteresis in stomatal aperture dynamics

Physical Review E, 2013
Stomata are pores responsible for gas exchange in leaves. Several experiments indicate that stomata synchronize into clusters or patches. The patches' coordination may produce oscillations in stomatal conductance. Previous studies claim to reproduce some experimental results.

Dynamic Preisach models of hysteresis

IEEE Transactions on Magnetics, 1988
Novel Preisach-type models of hysteresis are introduced. Their distinctive feature is their ability to describe dynamic properties of hysteresis nonlinearities. The identification problem of fitting dynamic Preisach models to experimental data is discussed. Some recommendations concerning numerical implementation of these models are given. >

Dynamical double hysteresis in weakly ionized magnetoplasmas

Physical Review A, 1992
We investigated experimentally the dynamical hysteresis in a weakly ionized rf magnetoplasma system by varying the frequency of the triangular modulation of the amplitude of rf voltage. The modulation covered a region consisting of two cascaded hysteresis loops with four different states. The high-frequency modulations cause finite delays of the onsets

Dynamic Response of Nonlinear Oscillators With Hysteresis

Volume 6: 11th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, 2015
The nonlinear features of the steady-state periodic response of hysteretic oscillators are investigated. Frequency-response curves of base-excited single-degree-of-freedom (SDOF) systems possessing different hysteretic restoring forces are numerically obtained employing a continuation procedure based on the Jacobian of the Poincaré map.

Qualitative modelling for dynamic magnetic hysteresis

2007 International Aegean Conference on Electrical Machines and Power Electronics, 2007
The studies of practical magnetic systems with hysteresis phenomenon are of great importance in electrical engineering. As an alternative to physical and empirical model, a qualitative model was constructed using adaptive fuzzy logic called adaptive network fuzzy inference system (ANFIS).

Dynamic hysteresis of a superparamagnetic nanoparticle

Physica B: Condensed Matter, 2004
Dynamic hysteresis in a nanoparticle is considered on the basis of the Brown's kinetic equation. Dependencies of the loop area on the frequency and amplitude of the magnetizing field and on temperature are presented and analyzed.
